Overview

What is a GRIT dust collector controller?

collector/kəˈlektər/noun
  1. One that collects.Merriam-Webster

  2. An automatic dust collector controller that receives commands from the GRIT Hub and starts, stops, or adjusts a compatible dust collection system through its existing control method.

What every Collector does

One job: match collection to demand.

Every Collector follows the same three-part path.

GRIT Collector
GRIT MagSwitch, iR/RF, Inline, and VFD Collector control hardware.

Inline-switching Collectors

Switch the collector’s power supply.

Use an inline Collector when the dust collection system plugs into a supported 120V or 220V circuit. Both models serve loads up to 15 amps. Match the voltage, current draw, phase, and connection.

Control-interface Collectors

Use the controls already there.

Use a MagSwitch, IR/RF, or VFD Collector when the dust collection system starts through a contactor, remote, or compatible MODBUS RTU drive instead of an inline outlet.

On-demand dust collection

Demand changes. Fan speed follows.

The GRIT Velocity System manages airflow and air-speed targets as tool and gate demand changes. In a configured variable-speed installation, the VFD Collector sends start, stop, or speed commands to a compatible drive so fan output follows the active airflow path.

A 20% reduction in fan speed can theoretically reduce fan power by 48.8%. Actual results depend on the installed fan, duct system, airflow requirements, and operating schedule.

Part of the GRIT system

Tool demand in. Dust collection responds.

A GRIT Trigger reports tool activity. The GRIT Hub applies the shop's rules. The GRIT Collector uses the matched control path to start, stop, or adjust the existing dust collection system.
